All good, that's what I was saying in my post is that I would go for the Pro but my ram is too tall and there's not enough clearance where the the non pro Dark Rock 4 doesn't extend over the ram and, as you said, will still be more than enough. I was just having problems with my old cooler that when my processor boosts to 4.9ghz it reaches 100°c as my cooler couldn't keep it cool.
